a study to assess the relative oral bioavailability of jnj-63623872 administered as oral concept formulations compared to the current tablet formulation

Conditions: Influenza A Virus

Summary: the purpose of this study is to compare the rate and extent of absorption of jnj-63623872 following administration of a single dose as three different concept formulations with that following administration of the current formulation, under both fed and fasted conditions, in healthy adult participants.

this is a phase 1, open-label, 2-panel, randomized, crossover study in healthy adult participants to assess the relative bioavailability jnj-63623872. the study population will consist of 48 healthy adult participants, equally divided over 2 panels: 24 participants in panel 1 and 24 participants in panel 2. participants will be randomized within each panel. participants will not be randomized between panels. panels 1 and 2 will be performed sequentially. participants having participated in one panel cannot also participate in the other panel. in panel 1, during 4 subsequent treatment sessions (periods i, ii, iii and iv), each participant will receive 4 treatments (treatments a, b, c, and d), randomized according to a classical 4 sequence, 4 period williams design. in panel 2, during 3 subsequent treatment sessions (periods i, ii and iii), each participant will receive 3 treatments (treatments e, f, and g) randomized according to a classical 6 sequence, 3 period williams design. primarily, pharmacokinetic parameters will be evaluated. participants' safety will be monitored throughout the study.
